REGENERATIVE GAS=BURNER.

SPECIFICATION forming part of Letters Patent No 392,527, dated November6, 1888.

To aZZ whom it may concern:

Be it known that I, HERB/[ANN SOHWIDLIN- SKY, a subject of the King ofPrussia, German Emperor, residing at Berlin, in the Empire of Germany,technician, have invented certain new and useful Improvements inRegenerative Gas-Lamps, of which the following is a com pletespecification.

My invention relates to gas burners in which the gas and the admittedair are heated; and the object of my invention is, first, to heatintensely the gas to be burned; secondly, to free it from allimpurities; thirdly, to heat thoroughly the admitted air, and, fourthly,to conduct this hot air before and behind the gas-flame.

Moreover, my invention covers a device applied to the chimney-tube,having for its purpose the regulating of the intensity of the annularflame.

The essential new features of my invention are, first, the dividedgas-chamber 9, formed by the top plate, a, provided with ribs 1' r, andthe bottom plate, b, provided with ribs 9-, the ribs 1- r bearing withtheir serrated edges upon the opposite plates, a and b, and letting thegas pass through these serrations; second, the serrations of the ribs r1- decreasing from the inlet to the outlet of the gaschambcr g; third,the chimneytube R, enlarged above the gas-chamber y and passing close tothe gasadmitting pipe 1); fourth, the inclined cross-plates w of thechimney-tube It; fifth, the flange a for spreading the flame; sixth, theregulating device fixed to the upper end of the chimney-tube R, andconsisting of the semiannular plates a n, Fig. 3,which are connected toeach other by means of the right-andleft-hand screw t.

In the annexed drawings, Figure 1 is a vertical section through y y" ofFig. 2 of the new gasburner; Fig.2,a horizontal section through a; 1/ zof Fig. 1. Figs. 3 and 4 are top views of the regulating device, andFig. 5 shows parts of the annular ribs 1' r.

The gas-chamber 9 consists of the top plate, a, provided with annularribs r r, and is screwed upon the bottom plate, I), which is alsoprovided with ribs rr. The edges of 50 the ribs 1' r',bearing upon theopposite plates,

1) and a, have serrations through which the gas (No model.)

passes. After unscrewing the plates a and b from each other theserrations of the ribs 1" r can easily be cleaned.

The size of the serrations of the ribs 9" r decreases from the inlet tothe outlet of the gaschamber g, so as to throttle the gas passingthrough these serrations and to heat it in tensely. Besides this, thegas leaves all impurities in the annular compartments formed by the ribsr '1" and enters the burnenpipesf thoroughly cleaned. An annularseries"of these burner-pipes f are in connection with the lastcon'lpartnieut of the gas-chamber g, as shown by Fig. 1.

To the bottom plate, I), of the gas-chamber g is attached, by means ofthe arms d, the globe holder A, to which the glass globe G is secured.The upper part of the globe-holder A forms the chamber for admitting theair to the flame. Between the cylindrical casing H, covering the burnerand the globe-holder A, is an annular space for the admission of the airto the air-chamber L,whcre the air is conducted to the upper part of theburner-pipes 7 5 f. A certain quantity of air passes through theintervals between the burner-pipes f and descends to the flame, whilethe remainder of the air passes to the outer part of the flame. By thisarrangement the air is, especially by means of the burner-pipes],intensely heated before flowing to the flame.

The center of the apparatus is occupied by the chimney-tube B, to thelower end of which is attached a spout, a The spout e ends in a flange,a, serving to spread the flame.

The regulating device secured to the upper end of the chimney-tube It isconstructed as follows; The semi-annular plates a a, sup ported by thechimney-tube B, are connected go to each other by means of therightand-lefthand screw t. By turning this screw it to the right or tothe left the plates at and n are made to approach or to recede from eachother, and the aperture of the chimney-piece, and with it the intensityof the flame, isthus consequently increased or decreased, The inclinedcross-plates w,disposed within the chimney-tube It, prevent dust fromfalling through the chimney-tube, and catch and collect the 10o sootproduced by the flame and regulate the ascension of thecombustion-gases.

The gas is conveyed to the gas-chamber '9 through the gas-pipe D,whichis connected to the'gas-main and provided with a cut-ofi" cock, 0. Thepipe D runs down close to the chimney-tube R, in order to heat the gasto be burned, and serves at the same time to suspend the burner incombination with the rodD.

I am aware that prior to my invention gaslamps with preparatory heatingof the gas and the combustion-air have been made. I therefore do notclaim such a lamp, broadly; but

WVhat I do claim as my invention, and desire to secure by LettersPatent, is-

1. In a regenerative gas-lamp,with preparatory heating of the gas andthe combustionair, the combination of the gas-chamber g with thecombustion-air chamber L, plate A, burner-tubesf, with spreading-sheetm, cylinder '0, with plate a, chimney R, with inclined crossbars 20 w, aregulating device, It '6, at the top of the chimney, gas-tube D, andglobe G, sub stantially as described and shown.

2. In a regenerative gas-lamp,with preparatory heating of the gas andthe combustionair, the combination of the gas-chamber g, be ing formedout of a top plate, a, with ribs r1, hawing saw-like notches,anda bottomplate,b, with ribs 1*,having similar notehes,saidplates being screwedtogether so that the ribs of one plate touch the other plate, with thecombustion-air chamber L, plate A, burner-tubes f, with spreadingsheetm, cylinder 1), with plate a, chimney R, with inclined erossbars' w w, aregulating device, t, at the top of the chimney, gas-tube D, and globeG, substantially as described.

3. In a regenerative gas-lamp,with preparatory heating of the gas andthe combustionair, the combination of the lamp-casing, the gas-chamberg, with the combustion-air chamber L, plate A,burner-tubes f, withspreadingsheet m, cylinder 1), with plate a, chimney R, arranged insidethelamp-casing and enlarged at its middle part above the gas-chamber g,inclined cross-bars w w in the same,a regulating device, 15, at the topof the chimney, gas-tube D, and globe G, substantially as described andset forth. I

4. In a regenerative gas-lamp,with preparatory heating of the gas andthe combustionair, the combination of the gas-chamber g with thecombustionair chamber L, plate A,burnertubes f, with spreading-sheet 1n,cylinder 21, with plate a, chimney B, with the regulating semicircularplates 42 a, and screw t, with right and left handed threads, theinclined cross'bars w w, gas-tube D, and globe G, substantially asdescribed.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
